Clinical Trial Summary

The investigators aim will be to compare the diagnostic performance of clinical visual examination (ICDAS II), intraoral/bite wing radiography (BW), near infrared light transillumination (NIR-LT), and laser fluorescence (LF), in comparison to microcomputed tomography (micro-CT) for the detection of non-cavitated occlusal enamel and dentin caries in third molar teeth. Potential participants will be consecutively recruited.


Clinical Trial Description

Studies regarding comparison of diagnostic techniques for caries detection are generally conducted under in vitro conditions due to ethical concerns. Considering the many recently published in vitro studies which attempted to assess the diagnostic ability of different caries diagnosis systems, it is not possible to know at what rate in vitro findings are applicable to the clinical situation.The investigators would like to assess initial occlusal caries lesions by using different diagnostic methods under in vivo conditions. In the present study, the investigators will assess diagnostic accuracy of clinical visual examination (ICDAS II), digital intraoral radiography, near infrared light transillumination (NIR-LT), and laser fluorescence (LF), by examining third molar teeth in comparison to gold standard micro-CT images. The null hypothesis of the study is that no significant difference exists for the clinical performance of the evaluated methods in detecting non-cavitated occlusal caries in either the enamel or the dentin. This prospective study will include 101 third molars of 101 patients with non-cavitated occlusal caries requiring extraction. ICDAS II, BW, NIR-LT and LF examinations will be carried out by two examiners. Gold standard will be determined by micro-CT imaging after extraction. Intraclass correlation coefficient (ICC) value will be calculated for examiner agreement. Accuracy rate, sensitivity, specificity, predictive values and areas under receiver operating characteristic curves (Az) will be calculated. Clinical application time and patient comfort/pain analysis will be compared. Nonparametric variables will be assessed by Kruskal Wallis Test. Significance level will be set at p<0.05. ;
